ABSTRACT:
The method of making a comminutor plate, particularly for pulp refining machines, includes the steps of arranging at least two separate annular support members concentrically and with radial spacing from each other, a set of elongated strip-shaped blades is arranged and welded in a predetermined relative distribution on the support members. A flowable solidifiable material is introduced in the spacing between the support members. The material is permitted to solidify to thus bind the support members to each other in the radial space therebetween.
